Definitions

the invention relates to an oscillating lawn sprinkler which is capable to be freely placed on the ground and to be connected with a water supply source in view of irrigating tilled areas such as lawns, gardens, etc.
a sprinkler of this type basically consists of a pipe featuring a number of spray perforations or nozzles, pivotally mounted on a bearing block and driven by the water pressure through a turbine-type motor enclosed in a sealed box.
the bearing block usually has a longitudinally extended shape, while the box containing the driving mechanism is mounted in correspondence of one of its ends in such a way as to be connected with the water supply source and, at the same time, act as a driving support for at least one of the ends of the oscillating pipe.
Mechanical control means are furthermore provided in the box containing the driving mechanism, which can be used to selectively confine the surface of the area to be watered.
control means are generally mounted on the inner side, ie. the one looking towards the spraying pipe, of the box containing the driving mechanism, just below the end part of the spraying pipe itself.
a further drawback of this type of sprinklers lies in the absence of a duly provided device for adjusting the water delivery rate. As a consequence, the user has therefore to rely solely on the water supply cock, by repeatedly having it more or less wide open, in order to adjust the water delivery rate of the sprinkler according to the usually varying needs.
sprinklers in general can be connected to water supply sources which are different from a drinking water supply conduit. For instance, they can be supplied with water from open irrigation canal through proper delivery pumps.
a filtering device to retain all such particulate contaminants and foreign matters as may be delivered with the water, which are likely to damage the turbine-like driving mechanism of the sprinkler.
a strainer is usually inserted at the end side of the water supply hose which has to be connected with the water supply intake fitting of the sprinkler by means of a ring nut.
strainer is again quite unconvenient in that it makes it rather difficult to clean its filtering surface when it becomes clogged.
the strainer is quite often fitted in a fixed way in the end fitting of the water supply hose and, in all cases where it can be removed, it becomes necessary to disassemble the whole fitting in order to be able to clean its filtering surface.
the sprinkler 4 shown in the Figures includes a bearing block 5 which supports the driving mechanism box 6 and the oscillating spray pipe 7.
the driving mechanism box 6 is of a traditional water-pressure type and includes all such components as required to operate the spray pipe 7 (eg. the turbine-like motor, the mechanism to adjust the oscillating range of the spray type, etc.), which are already well-known and therefore do not require any further description. It should be sufficient here to remember that the sprinkler 4 is operated by the pressure that the water flowing into the driving mechanism bos 6, through the inlet connection 8, imparts on the blades of a turbine-like motor which is mechanically linked with the spray pipe 7.
the spray pipe 7 eg. the turbine-like motor, the mechanism to adjust the oscillating range of the spray type, etc.
said driving mechanism box 6 is already duly fitted with both the afore mentioned device to adjust the oscillating range of the spray pipe 7, through the actuation of the control knob 9, and a suitable device to further adjust the flow rate of the water delivered by the spray pipe 7 itself.
Said water-flow adjusting device comprises a sleeve 10 which is pressed through two pipe unions 11, 12 (Fig.3) that are provided in the wall of the driving mechanism box 6.
Said sleeve 10 is provided with annular grooves 13, 14 to accomodate corresponding sealing rings 15, 16 and it features two opposed openings (only one opening 17 is shown in Fig. 3) having an elongated shape and capable of letting the supply water flow from the driving mechanism box 6 to the spray pipe 7.
the open end of the spray pipe 7 is attached by pressure fitting to the inwardly facing end of the sleeve 10.
Said valve 21 is essentially formed by a stem 22, on the inner end of which two opposed tabs 23, 24 are provided which are capable to throttle the water passage openings 17.
valve stem 22 The outer end of the valve stem 22 is provided with a retaining collar 25 and an adjustment knob 26.
Said valve 21 is simply fitted into the sleeve 10, where it is retained by its collar 25 engaging as a spring latch into the afore mentioned groove 18 of the sleeve 10, as well as by two spring tabs 27, 28 which are capable to co-operate with the inner edge of the pipe union 12 in order to prevent the sleeve 10 to be accidentally extracted from the driving mechanism box 6.
the throttling tabs 23, 24 of the valve 21 show a surface which is tapered toward their free end in order to enable also small flow-rate variations to be accomplished.
said tabs 23, 24 can be rotated over the whole range between two extreme settings, ie. for full and minimum water flow-rate repectively, in correspondence of each one of them a radial projection 29 of the knob 26 strikes against the longitudinal edges of the afore mentioned axial projection 19 of the sleeve 10, thereby creating corresponding positive limit stops.
the device provided for adjusting the oscillating range of the spray pipe 7 is essentially of a known type, except for its being peculiarly arranged on that side of the driving mechanism box 6 which is opposed to the one where the end of the spray pipe 7 is connected, as well as its being mechanically linked with the previously described sleeve 10.
a flange 30 is integrally obtained which is capable of linking the device for the adjustment of the oscillating range (knob 9 and linking rods connected with it) with the sleeve 10 supporting one end of the spray pipe 7.
the sprinkler according to the present invention is designed in such a way as to allow for a more convenient arrangement of the water filtering device inside the pipe union 8 provided for the connection of the water supply hose.
said pipe union 8 is made in the form of a "male-type” connection fitting (Fig.3) to be snap-fitted into a corresponding "female-type” fitting attached to the end of the water supply hose (not shown in the Figures).
a counterbore 31 is provided inside the hose-connection fitting 8 , against which the open edge 32 of a cartridge strainer 33 can rest.
This cartridge strainer can therefore be inserted in an easily removable way into the water supply conduit of the sprinkler itself (Fig.1).
the objects of the invention can be considered as fully reached through the provision of a device for adjusting the water delivery flow-rate, as well as through the arrangement of all user controls of the sprinkler on a much more convenient location.
the object is furthermore reached of obtaining a water filtering device which is made independent of any part or component outside the sprinkler itself and is housed in an easily removable way inside the water supply conduit of the sprinkler.
